“A time-weighted average
is used to calculate a workers daily exposure to a hazardous substance (such as
chemicals, dusts, fumes, mists, gases, or vapors) or agent (such as noise),
averaged to an 8-hour workday, taking into account the average levels of the substance or agent and the time spent in the area”. Time Weighted
Average us also known as a WEL (Workplace Exposure Limit). Time Weighted
average is broken up into two categories, The LTEL (Long Term Exposure Limits),
and STEL (Short Term Exposure Limits). The LTEL is the highest amount of a dose
an organism can stand in an 8 hour work day. The main goal of an STEL is to
prevent adverse health effects and other unwanted affects. There is a
predicament. Most workers work longer than 8 hours a day and 40 hours a week. They
counteract that by putting restraints on how long you can work at a given time,
by providing longer breaks and less time with the substance you are exposed
too. To learn more about Time weighted averages click here…. Time Weighted Average extra info
